A) \[HN{{O}_{3}}\]
B) \[HCO_{3}^{-}\]
C) \[{{H}_{2}}O\]
D) \[N{{H}_{3}}\]
Correct Answer: A
Solution :
\[HN{{O}_{3}}\] (nitric acid) is generally not an amphoteric substance. It is a strong acid (proton-donating) though sometimes, in presence of stronger acid, it also act as base (e.g. in nitration of aromatic compounds. It act as a base and accept proton form \[{{H}_{2}}S{{O}_{4}}\]). However \[HCO_{3}^{-},\,{{H}_{2}}O\] and \[N{{H}_{3}}\] frequently act both as an acid as well as a base (i.e. amphoteric in nature)
